Method for generating eight kinds of code by combined three keys

Abstract

The invention designs a method of generating eight coding via the combination of three keys. Two keys of three keys are function keys called as the function key 1 and the function key 2 respectively. Another key is a status key. Eight coding is called as the coding 1, the coding 2, the coding 3, etc. The combination of the three keys has corresponding coding as follows: if the function key is not pressed down, the function key 1 is clicked once to generate the coding 1; the function key 1 is clicked twice to generate the coding 2; the function key 2 is clicked once to generate the coding 3; and the function key 2 is clicked twice to generate the coding 4; and if the function key is pressed down, the function key 1 is clicked once to generate the coding 5; the function key 1 is clicked twice to generate the coding 6; the function key 2 is clicked once to generate the coding 7; and the function key 2 is clicked twice to generate the coding 8. The invention can generate eight coding without adding a key. In addition, the invention alters software only without changing the structure of a mouse in order to achieve the purpose of increasing an input signal. Therefore, manufacturing cost can be saved greatly.

Description

technical field [0001] The invention relates to a coding method for a key combination of an input device, in particular to a coding method for a key combination of a mouse and a joystick. Background technique [0002] At present, the buttons of the mouse and the joystick are relatively few, generally 3. In order to enable it to input more information, more buttons have been added, but because the number of fingers is only 5 and there are requirements for holding them, the Use 3 finger keys, so the added keys cannot be placed in a convenient position for pressing. Contents of the invention [0003] In order to solve above-mentioned defective, the present invention has designed the method that three key combinations generate eight kinds of codes. Two of the three keys are function keys, which are called function key 1 and function key 2 respectively, and the other is a status key. The eight codes are called code 1, code 2...code 8; three-key combinations and corresponding c...
